BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a method and a circuit for physicaluplink transmission for 3GPP long term evolution (LTE), and morespecifically, to a method and a circuit generally adept at remappingphysical uplink control channels for both of a resource block containingacknowledgement and non-acknowledgement (ACK/NAK) channel and a mixedresource block containing the ACK/NAK channels and channel qualityindication (CQI) channels.

2. Description of the Related Art

Orthogonal Frequency Division Multiplexing (OFDM) is a popular wirelesscommunication technology for multiplexing data in the frequency domain.

The total bandwidth in an Orthogonal frequency-division multiplexing(OFDM) system is divided into narrowband frequency units calledsubcarriers. The number of subcarriers is equal to the FFT/IFFT size Nused in the system. Generally, the number of subcarriers used for datatransmission is less than N because some of the subcarriers at the edgeof the frequency spectrum are reserved as guard subcarriers, andgenerally no information is transmitted on these guard subcarriers.

The Third Generation Partnership Project Long Term evolution (3GPP LTE)is a project within the Third Generation Partnership Project to improvethe Universal Mobile Telecommunications System mobile phone standard tocope with future requirements. In the standards of the physical uplinkof 3GPP LTE (long term evolution), one type of the resources used fortransmitting the uplink control channel (PUCCH) is known as a cyclicshift (CS) for each OFDM symbol. One of important aspects of the systemdesign is resource remapping on either a symbol, slot or subframe-level.

The following three references are cited as being exemplary ofcontemporary practice in the art:

-   Reference [1], R1-081155, “CR to 3GPP spec 36.211 Version 8.1.0”,    RAN1#52, February 2008, Sorrento, Italy, describes the standards of    the physical channels for 3GPP, and chapter 5.4.1 will be cited in    the following specification in order to illustrate the contemporary    slot-level remapping method for the acknowledgement and    non-acknowledgement (ACK/NAK) channel in the physical uplink of 3GPP    LTE system.-   Reference [2], R1-080983, “Way-forward on Cyclic Shift Hopping    Pattern for PUCCH”, Panasonic, Samsung, ETRI, RAN1#52, February    2008, Sorrento, Italy, discloses methods for remapping either a    resource block containing only ACK/NAK channel or a resource block    containing both CQI and ACK/NAK channels.-   Reference [3], R1-073564, “Selection of Orthogonal Cover and Cyclic    Shift for High Speed UL ACK Channels”, Samsung, RAN1#50, August    2007, Athens, Greece, teaches a scenario for data transmission for    high speed uplink ACL/NAK channel by using a subset of the    combination of the cyclic shift and the orthogonal cover.-   Reference [4], R1-080707, “Cell Specific CS Hopping and Slot Based    CS/OC Remapping on PUCCH”, Texas Instruments, Feb. 11-15, 2008,    Sorrento, Italy, teaches cyclic shift (CS) hopping and slot based    cyclic shift/orthogonal covering (CS/OC) remapping for PUCCH format    0 and 1, i.e. in the context of uplink ACK/NAK transmissions in    correspondence to downlink packets.

The methods of the slot-level resource remapping recently proposed, forexample as disclosed in references [2] and [3], have been included inthe 3GPP standards as shown in reference [1]. One of the shortages oftransmission capacity in wireless telecommunication networks is that thecontemporary remapping methods for resource blocks containing controlchannels are designed exclusively for either ACK/NAK resource blockswith the extended cyclic prefix or for normal cyclic prefix cases wherea mixed resource block containing both of the ACK/NAK and CQI channels,but contemporary remapping methods are not applicable for both. Thisshortage in transmission capacity prevents the contemporary techniquesfrom being readily adapted to a complex 3GPP LTE physical uplink whereACK/NAK resource blocks may be applied by the extended cyclic prefix,adapted to a complex 3GPP LTE physical uplink where mixed resourceblocks (where the ACK/NAK and CQI channels coexist) may be applied bythe normal cyclic prefix, and adapted to a complex 3GPP LTE physicaluplink where mixed resource blocks (where the ACK/NAK and CQI channelscoexist) may be applied by the extended cyclic prefix.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION

A simplified example of data transmission/reception using OrthogonalFrequency Division Multiplexing (OFDM) is shown in FIG. 1.

At the transmitter, the input data to be transmitted is modulated by aquadrature amplitude modulation (QAM) modulator 111. The QAM modulationsymbols are serial-to-parallel converted by a serial-to-parallelconvertor 113 and input to an inverse fast Fourier transform (IFFT) unit115. At the output of IFFT unit 115, N time-domain samples are obtained.Here N refers to the sampling number of IFFT/FFT used by the OFDMsystem. The signal transmitted from IFFT unit 115 is parallel-to-serialconverted by a parallel-to-serial convertor 117 and a cyclic prefix (CP)119 is added to the signal sequence. The resulting sequence of samplesis referred to as the OFDM symbol. Serial to parallel convertor 113 usesshift registers to convert data from serial form to parallel form. Datais loaded into the shift registers in a serial load mode, and is thenshifted parallel in a shift mode with a clock signal.

At the receiver, the cyclic prefix is firstly removed at cyclic prefixremover 121 and the signal is serial-to-parallel converted byparallel-to-serial convertor 123 before feeding the converted parallelsignal into fast Fourier transform (FFT) transformer 125. Output of FFTtransformer 125 is parallel-to-serial converted by parallel-to-serialconvertor 128 and the resulting symbols are input to QAM demodulator129. Parallel to serial convertor 123 uses shift registers to convertdata from parallel form to serial form. Data is loaded into the shiftregisters in a parallel load mode, and is then shifted serially in ashift mode with a clock signal.

The total bandwidth in an OFDM system is divided into narrowbandfrequency units called subcarriers. The number of subcarriers is equalto the FFT/IFFT size N. In general, the number of subcarriers used fordata is less than N because some of the subcarriers at the edge of thefrequency spectrum are reserved as guard subcarriers, and no informationis transmitted on guard subcarriers.

FIG. 2 is a block diagram of a simplified example of data transmission,data reception and signal processing stages using Orthogonal FrequencyDivision Multiplexing (OFDM). As shown in FIG. 2, the OFDM symbolsoutput from cyclic prefix (CP) 119 are further processed by signalprocessing unit_Tx 120 before being transmitted by the transmittingantennas. Similarly, the processed OFDM symbols transmitted from thetransmitter are firstly processed by signal processing unit_Rx 122before received by the receiving antennas. Signal processing unit_Tx 120and signal processing unit_Rx 122 perform signal processing respectivelyfor the transmitter and the receiver in accordance with certain signalprocessing schemes.

In the uplink of 3GPP LTE standards, one type of the resource used inthe uplink control channel (PUCCH) is known as a cyclic shift (CS) foreach OFDM symbol. PUCCHs are defined as channels carrying controlsignals in the uplink, and PUCCHs may carry control information, e.g.,channel quality indication (CQI), ACK/NACK, hybrid automatic repeatrequests (HARQ) and uplink scheduling requests.

The physical uplink control channel, PUCCH, carries uplink controlinformation. All PUCCH formats use a cyclic shift (CS) of a sequence ineach OFDM symbol. FIG. 3 is an illustration showing an example ofmultiplexing six user equipments (UEs) into one resource blockcontaining channel quality indication (CQI) signals within one slot. InFIG. 3, the PUCCH occupies twelve subcarriers in the resource block andtwelve cyclic shift resources (c₀ through c₁₁) exist in the resourceblock. The CQI signals include both of CQI data signals (e.g., CQI datasignal 201) occupying several symbol elements (e.g., s₀) within the OFDMsymbols and CQI reference signals (e.g., CQI reference signal 202)occupying several symbol elements (e.g., s₁). Six UEs (i.e., UE 1through UE 6) are multiplexed in the resource block. Here, only six outof twelve cyclic shifts are actually used.

FIG. 4, cited from reference [3], shows the contemporary workingassumption on the transmission block of uplink ACK/NAK channels andreference signals. Here, the position of the reference signal long blockis not determined, therefore, FIG. 4 is only for illustrative purposes.ACK/NAK signals and the uplink reference signals (UL RS) for ACK/NAKdemodulation are multiplexed on code channels 301 constructed by both acyclic shift of a base sequence (e.g., Zadoff-Chu sequence) and anorthogonal cover. ACK/NAK signals and the uplink reference signals aremultiplexed on code channels 301 constructed by both of a Zadoff-Chusequence ZC(u,τ) and an orthogonal cover. For ACK/NAK channels, aZadoff-Chu sequence ZC(u,τ) with a particular cyclic shift τ, ZC(u,τ) isplaced in sub-carriers and an orthogonal cover is applied to time domainlong block (LB). The IFFTs transform a frequency domain representationof the input sequence to a time domain representation. The orthogonalcover may be used for both of UL RS and for PUCCH data, the actual codeof the orthogonal cover is different from {w₀, w₁, w₂, w₃} which is usedonly for PUCCH data.

Here, FIG. 3 shows an example of a contemporary mapping methodexclusively adapted to resource blocks only containing CQI channels, andFIG. 4 shows an example of a contemporary mapping method for ACK/ANCKchannels.

One important aspect of system design is resource remapping on a symbol,slot or subframe-level. The slot-level resource remapping methods havebeen proposed in, for example, references [2] and [3], and have beenincluded in the current Change Request to the specification in reference[1].

. . . The physical resources used for PUCCH depends on two parameters,N_(RB) ⁽²⁾ and N_(cs) ⁽¹⁾, given by higher layers. The variable N_(RB)⁽²⁾≧0 denotes the bandwidth in terms of resource blocks that arereserved exclusively for PUCCH formats 2/2a/2b transmission in eachslot. The variable N_(cs) ⁽²⁾ denotes the number of cyclic shift usedfor PUCCH formats 1/1a/1b in a resource block used for a mix of formats1/1a/1b and 2/2a/2b. The value of N_(cs) ⁽¹⁾ is an integer multiple ofΔ_(shift) ^(PUCCH) within the range of {0, 1, . . . , 8}, whereΔ_(shift) ^(PUCCH) is defined in section 5.4.1. No mixed resource blockis present if N_(cs) ⁽¹⁾=0. At most one resource block in each slotsupports a mix of formats 1/1a/1b and 2/2a/2b. Resources used fortransmission of PUCCH format 1/1a/1b and 2/2a/2b are represented by thenon-negative indices n_(PUCCH) ⁽¹⁾ and

${n_{PUCCH}^{(2)} < {{N_{RB}^{(2)}N_{sc}^{RB}} + {\left\lceil \frac{N_{cs}^{(1)}}{8} \right\rceil \cdot \left( {N_{sc}^{RB} - N_{cs}^{(1)} - 2} \right)}}},$

respectively.

5.4.1 PUCCH Formats 1, 1a and 1b

For PUCCH format 1, information is carried by the presence/absence oftransmission of PUCCH from the UE. In the remainder of this section,d(0)=1 shall be assumed for PUCCH format 1.

For PUCCH formats 1a and 1b, one or two explicit bits are transmitted,respectively. The block of bits b(0), . . . , b(M_(bit)−1) shall bemodulated as described in section 7.1, resulting in a complex-valuedsymbol d(0). The modulation schemes for the different PUCCH formats aregiven by Table 5.4-1.

The complex-valued symbol d(0) shall be multiplied with a cyclicallyshifted length N_(seq) ^(PUCCH)=12 sequence r_(u,v) ^((α))(n) accordingto:

y(n)=d(0)·r _(u,v) ^((α))(n), n=0, 1, . . . , N _(seq) ^(PUCCH),  (1)

where r_(u,v) ^((α))(n) is defined by section 5.5.1 with M_(sc)^(RS)=N_(seq) ^(PUCCH). The cyclic shift a varies between symbols andslots as defined below.

The block of complex-valued symbols y(0), . . . , y(N_(seq) ^(PUCCH)−1)shall be block-wise spread with the orthogonal sequence w_(n) _(oc) (i)according to

z(m′·N _(SF) ^(PUCCH) ·N _(seq) ^(PUCCH) +m·N _(seq) ^(PUCCH) +n)=w _(n)_(oc) (m)·y(n),  (2)

where

-   -   m=0, . . . , N_(SF) ^(PUCCH)−1    -   n=0, . . . , N_(seq) ^(PUCCH)−1    -   m′=0,1        and N_(SF) ^(PUCCH)=4. The sequence w_(n) _(oc) (i) is given by        Table 5.4.1-1.

Resources used for transmission of PUCCH format 1, 1a and 1b areidentified by a resource index n_(PUCCH) ⁽¹⁾ from which the orthogonalsequence index n_(oc)(n_(s)) and the cyclic shift α(n_(s)) aredetermined according to:

In the present invention, novel slot-level remapping methods areproposed to provide a better intra-cell randomization, especially forACK/NAK resource blocks with extended cyclic prefix, and for normalcyclic: prefix cases with mixed resource block where the ACK/NAK and CQIcoexist in a single resource block. Method A and Method B are proposedas below.

Equations (8) and (9) are referred by the present invention.

Accordingly, the drawings anddescription are to be regarded as illustrative in nature, and not asrestrictive. The invention is illustrated by way of example, and not byway of limitation, in the figures of the accompanying drawings.
